Paperwork should never eat the work.
SyncBook exists so agencies, consultancies and studios get paid for everything they agree to. We build the commercial ledger that sits under every engagement - locking what was signed, flagging what drifted, and billing what was approved.
We believe the commercial record should be as solid as the work, not a trail of half-remembered emails and spreadsheets that quietly leak margin.
From goodwill to guarded scope
Service businesses run on trust, and trust quietly turns into free work. An extra revision here, a "quick favour" there, a retainer that slowly doubles in scope. None of it is malicious. All of it is expensive.
The missing layer
Proposal tools stop at the signature. Invoicing tools start after the work. SyncBook is the layer in between: a live, immutable ledger that connects what was signed to what was done to what was billed, with an agent that drafts the paperwork and a human who always approves it.
Built on four convictions.
These aren't marketing lines, they're constraints in the product. Every feature in SyncBook answers to them.
A signed scope is a contract, not a suggestion
Once a client accepts, the baseline is sealed with a fingerprint. Commercial records shouldn't be editable by anyone, including us.
Drift is data, not awkwardness
Out-of-scope requests aren't a relationship problem to tiptoe around. They're new work with a price, and they deserve a paper trail.
Approval is always human
AI should draft, flag and prepare, never send, charge or agree. Every client-facing action in SyncBook waits for a person to say yes.
One ledger, not four tools
Proposals, scope tracking, change orders and invoicing are one commercial story. They should live in one record that traces back to what was signed.
